Abstract
The orange carotenoid protein (OCP) and its derivative, the red carotenoid protein (RCP), appear to play important photoprotective roles in cyanobacteria. Structural and functional characterization is gradually elucidating the specific details of how carotenoid-protein interactions, including the role of six methionine residues oriented toward the pigment, contribute to the spectral and functional properties of these proteins.
摘要
橙色类胡萝卜素蛋白（OCP）及其衍生物红色类胡萝卜素蛋白（RCP）似乎在蓝细菌中发挥着重要的光保护作用。结构和功能表征正在逐步阐明类胡萝卜素与蛋白质相互作用的具体细节，包括六个朝向色素的甲硫氨酸残基的作用，这些相互作用如何影响这些蛋白质的光谱和功能特性。
